FIELD OF THE INVENTION

The described embodiments relate to communications. More specifically, the described embodiments relate to enhancing a relay node with additional backhaul alternatives and selections.

BACKGROUND

In some deployments a base station may not have access to a wired (for example fiber) or wireless (for example point to point microwave) backhaul that satisfies the data network access requirements from a plurality of user equipment that is connected to the base station over a wireless access technology (for example cellular). In some deployments the access traffic of a base station is backhauled from the base station through a second base station (for example a donor base station) over the wireless access technology (this scenario is typically called a relay node or relay base station). In these cases the wireless access resources will be shared between the user equipment for the base station and the second base station and the backhaul of the access traffic from the base station. Typically wireless access technology resources are at a premium and the duplication may not be efficient. In some scenarios the quality of the link between the base station and the second base station is not sufficient or adds latency for/to the end to end link or the interference of the additional backhaul through the wireless communication technology degrades the overall wireless system. Therefore it is desirable to have improved systems and methods enhancing backhaul for relay nodes of wireless communication networks.

DETAILED DESCRIPTION

FIG. 1 shows a wireless communication system, according to an embodiment. The system includes a plurality of base stations (BSs) 100, 101, 110, 111, 112. In at least some embodiments the system includes a homogeneous system, wherein the BSs are of the same type (or alternatively classification or tier, etc.). In at least some embodiments the system includes a plurality of BSs types, such as Macro BSs 100, 101 and small cell (SC) BSs 110, 111, 112. In at least some embodiments Macro BSs 100, 101 have a larger coverage area or cell size, or transmit larger power, or have higher performance antenna systems, etc. than the small cell BSs 110, 111, 112. In at least some embodiments the small cell BSs are alternatively called microcell, picocell, relay node, or femtocell BS. In at least some embodiments the small cell BSs are located indoors (inside an enterprise, commercial building, home), such as small cell BS 112.

For at least one embodiment the BS includes a traditional BS, wherein a large portion of the radio access network (RAN) functionality, such as radio frequency (RF), analog and digital baseband and scheduling are co-located. For at least one embodiment at least a portion of the BS functionality is implemented at a second location. For at least one embodiment the BS includes distributed processing elements, such as one or more of remote radio heads (RRH), remote radio units (RRU) or distributed antenna systems (DAS). For at least one embodiment scheduling, resource allocation or baseband processing associated with one or more BS are aggregated at a second location, for example a cloud BS or cloud RAN.

In at least some embodiments the plurality of BSs wirelessly communicate with a plurality of user equipment (UE) device, such as UE device 121 (wirelessly communicating with BS 100), UE device 122 (wirelessly communicating with BS 111), UE device 123 (wirelessly communicating with BS 112). The wireless communication access traffic (or data or data payload) associated with UE devices 121, 122, 123 may be associated with one or more data networks 140, 141, 142 (for example a carrier network, or a company network, or the internet, or a core network). The wireless communication access traffic may include downlink (originating from the data network 140, 141, 142) or uplink (originating from the UE devices 121, 122, 123) or both downlink (DL) and uplink (UL) traffic. For at least one embodiment the wireless communication access traffic (or the backhaul traffic) include data associated (for example originating from or terminating at) with the UE device or control information associated with the wireless communication system (for example the X2 interface from the 4G or LTE wireless communication technology). Examples of control information associated with the wireless communicating system includes link performance (for example information associated with received signal quality, path loss, channel between desired BS and one or more UE device or backhaul UE (bUE) device, SNR, interference, interference sources, etc.), traffic/data (for example information associated with QoS, packet delay, traffic loading, jitter, queue states or sizes, PER, etc.).

In at least some embodiments the wireless communication access traffic is communicated to a data network 140, 141, 142, through a backhaul communication technology, such as backhaul 130, 131, 132, 133, 134. The backhaul communication technology may include one or more of a fiber communication technology, a microwave link, a T1/E1, a cable or DSL communication technology or an alternative inband or out of band wireless (for example WiMAX or WiFi) communication technology. In at least some embodiments the backhaul requirements for a BS include parameters associated with the BS or a plurality of UE devices associated with the BS. In at least some embodiments BS 100 may include a large coverage area, and a high density plurality of UE devices and include 2G/3G/4G wireless communication technology. For example BS 100 aggregate access traffic may be large and may require a Backhaul 130 with large bandwidth (for example a fiber communication technology or a microwave communication technology). In at least some embodiments BS 100 includes a small coverage area (for example a home), and a small number of UE devices and include 4G wireless communication technology. For example BS 100 aggregate access traffic may be small and may require a Backhaul 130 with small bandwidth (for example a DSL communication technology or a cable modem communication technology). In at least some embodiments the backhaul requirements associated with a BS includes one or more of a latency, a bandwidth, a PER (packet error rate), a packet jitter, a cost, a data cap, etc. In at least some embodiments the access traffic associated with the plurality of UE devices associated with a BS includes a plurality of backhaul requirements. For example a first UE device may be streaming video, which may require large bandwidth, but relaxed latency and PER requirements. For example a second UE device may be performing VoIP, which may require low latency, and small bandwidth. In at least some embodiments the backhaul associated with a BS (for example one or more of BS 100, 101, 110, 111, 112) may not satisfy the access traffic requirements of the plurality of UE devices associated with the BS. In at least some embodiments a BS may not have access to so-called traditional backhaul (such as T1/E1, microwave, fiber) or traditional backhaul installation time or installation costs are too high.

FIG. 2 shows an embodiment of a backhaul system, according to an embodiment. The system includes a base station (BS) 201 and a plurality of backhaul user equipment (bUE) devices (such as bUE devices 210, 211), each of the plurality of bUE devices 210, 211 operable to wirelessly communicate with the BS (201) through at least a first communication technology (for example wireless communication technologies (WCT) 220, 221 and 222), and the plurality of bUE devices 210, 211 each operable to communicate with at least one data network (such as data networks 241, 242) through at least a second communication technology (for example backhaul communication technologies (CT) 230 and 231). For an embodiment, the BS (201) is operative to wirelessly communicate (for example wireless communication technologies (WCT) 222) with one or more user equipment (UE) devices (such as, UE device 212), and network connect the one or more UE devices (such as, UE device 212) to the at least one data network (241, 242) through one or more of the plurality of bUE devices 210, 211, select one or more of the plurality of bUE devices 210, 211 for backhaul (BH) traffic, wherein the BH traffic includes access traffic associated with the one or more UE devices (such as, UE device 212), aid in selecting a transmission power level of at least one of the plurality of bUE devices 210, 211, or at least one of the one or more UE devices (such as, UE device 212), and transmit resource block (RB) scheduling information for the BH traffic of at least one of the plurality of bUE devices 210, 211 and the access traffic of at least one of the one or more UE devices (such as, UE device 212).

It is to be understood that while FIG. 2 only shows a single UE device 212, embodiments include the BS 201 wirelessly communicating with any number of UE devices. Further, while FIG. 2 only shows two bUE devices 210, 211, embodiments includes any number of bUE devices operable to wirelessly communicate with the BS 201. Further, while FIG. 2 depicts the BS 201 operable to perform several steps, it is to be understood that embodiments include the operational steps being performed or aided by other devices. For example, the steps of selecting one or more of the plurality of bUE devices 210, 211 for backhaul (BH) traffic, and selecting a transmission power level of at least one of the plurality of bUE devices 210, 211 can alternatively be wholly or partially performed somewhere else, such as, at a base station controller or in the cloud (for example at a cloud RAN or at a cloud BS).

In at least some embodiments the access traffic associated with UE device 212 (or a plurality of UE devices) includes a plurality of applications (for example streaming video, VoIP, browsing, gaming, etc.), each of which may include one or more plurality of access traffic requirements (for example delay QoS, best effort, foreground, background, DL, UL, etc.) and may map into a set of backhaul requirements for selecting the bUE device. For example UE device 212 may need to upload (access traffic UL) a large file in the background. For this example a first bUE device may include a high bandwidth and high PER backhaul WCT link on the DL (for example a 4G/LTE link limited by bursty interference from aggressive frequency reuse) and a second bUE device may include a low bandwidth and low PER WCT link on the DL (for example a 3G link limited by low SNR). For this example the access traffic requirements are better matched (or alternatively mapped or satisfied) by the first bUE device. For example UE device 212 application may include a VoIP (typically with low bandwidth, symmetrical DL/UL, low latency access traffic requirements). For this example a first bUE device may include a high bandwidth, high latency and high jitter backhaul CT to a VoIP gateway (for example over a cable modem to a cable operator to a VoIP gateway) and a second bUE device may include a low bandwidth, low latency and low jitter CT link (for example a T1 to a core network). For this example the VoIP access traffic requirements are better matched (or alternatively mapped or satisfied) by the second bUE device.

For at least one embodiment the bUE device 210 wirelessly communicates with the BS 201 on the same wireless technology (for example 4G or LTE) as the UE device 212 wirelessly communicates with the BS 201 but on a different channel or carrier. For at least one embodiment the bUE device 210 wirelessly communicates with the BS 201 on the first wireless technology (for example 4G/LTE) as the UE device 212 wirelessly communicates with the BS 201 on a second wireless technology (for example 3G/HSPA).

For at least one embodiment a small cell BS (for example one or more of a microcell, a picocell, a relay node, femtocell) includes client side modem functionality (for example a subset of a UE device or bUE device functionality). For at least one embodiment the small cell BS includes a backhaul CT to one or more data networks. For these embodiments a small cell BS with client side modem functionality could function as a bUE device. For at least one embodiment each of the first BS and the small cell BS including bUE device functionality include backhaul CT and the access traffic associated with the first BS could be communicated over the WCT through the small cell BS including bUE device functionality. For at least one embodiment each of the first BS and the small cell BS including bUE device functionality include backhaul CT and the access traffic associated with the small cell BS including bUE device functionality could be communicated over the WCT through the first BS. For at least one embodiment each of the first BS and the small cell BS including bUE device functionality include backhaul CT and the access traffic associated with the small cell BS including bUE device functionality is communicated over the first BS backhaul CT or the small cell BS backhaul CT based on first parameters of the first BS backhaul CT or second parameters of the small cell BS backhaul CT. For at least one embodiment the first parameters or second parameters include one or more of bandwidth, latency, PER, jitter, QoS, cost, sponsoring, rebates. At least some embodiments of both FIG. 2 and FIG. 3 utilize these embodiments.

For at least one embodiment accessing a data service (for example video streaming, cloud back-up, software update) over one or more data networks and one or more backhaul CT includes a common operator with improved control of parameters (for example latency, bandwidth, PER). This is typically the case for wireless service providers with carrier class backhaul CT (for example fiber CT, microwave CT, T1/E1) to mobile core or core networks. For at least one embodiment accessing a data service (for example video streaming, cloud back-up, software update) over one or more data networks and one or more backhaul CT includes a plurality of operators with a plurality of control of parameters (for example latency, bandwidth, PER).

For example the access or backhaul WCT may be one of 2G or 3G WCT and the backhaul CT may be a 4G WCT). For at least one embodiment the bUE device may be a UE device (for example a smartphone or tablet or notebook) with one or more of 2G, 3G, 4G cellular access WCT and one or more of WiFi, Bluetooth, USB, Ethernet backhaul CT. For at least one embodiment the one or more of WiFi, Bluetooth, USB, Ethernet backhaul CT may be configured to connect to one or more of a WiFi access point, or a Ethernet LAN over a Bluetooth or a USB or Ethernet modem. Clearly many other permutations or combinations of one or more WCT and one or more backhaul CT are possible. For at least one embodiment the bUE device is a dedicated (or alternatively called a specialized or custom) device to improve the performance of the backhaul WCT link or backhaul CT link or the connection (for example by performing one or more of the following functions: collecting additional information, mapping, bridging, routing, network connecting, controlling) between the backhaul WCT and the backhaul CT. For example the dedicated bUE device may improve the backhaul WCT by improving hardware or software capability (for example increased transmit power, lower receiver noise figure, additional transmit or receiver antennas, higher antenna gain, improved link performance statistics gathering and exchange), by improving the installation or deployment of the bUE device for better signal quality parameters (lower path loss, lower interference, etc.), by deploying the dedicated bUE device at a location with favorable backhaul CT parameters (for example at closer to a cable or DSL head-end for improved data communication performance) or by improving the connection between the backhaul WCT and the backhaul CT (for example by improved packet processing, protocol conversion, header conversion, PER monitoring, ARQ handling, QoS mapping, etc.).

For at least one embodiment, the BS 201 is further operative to obtain one or more first parameters associated with the wireless communication between one or more of the plurality of bUE devices 210, 211 and the BS 201. Specifically, for at least one embodiment, the selection of the one or more of the plurality of bUE devices 210, 211 for the BH traffic is based on the first parameters. At least some embodiments of both FIG. 2 and FIG. 3 implement these embodiments.

In at least some embodiments selecting the bUE device (such as, one of bUE device 210, 211) is based on a bUE device backhaul wireless communication technology (WCT) between the plurality of bUE devices 210, 211 and the BS 201. For example bUE device 210 may include a WCT 220 with large bandwidth (exemplary first parameter) (for example 4G or LTE) and bUE device 211 may include a WCT 221 with low PER (exemplary first parameter) (for example 2G/3G). For this example bUE device 210 may be better suited for a streaming video application and bUE device 211 may be better suited for a VoIP or gaming application. For example bUE device 210 may include a WCT 220 with a high SNR (exemplary first parameter) and bursty interference (exemplary first parameter) (for example 4G/LTE with aggressive frequency reuse resulting in high average throughput and high PER and frequent retransmissions) and bUE device 211 may include a WCT 221 with low average and low variance CQI (channel quality information) (exemplary first parameter). For this example bUE device 210 may be better suited for video streaming and bUE device 211 may be better suited for VoIP application. In at least some embodiments the bUE device 210 may include a WCT 220 with low interference footprint (for example by using directional antennas or low transmission power which results in lower interference to other surrounding WCT links) (exemplary first parameter), which could make it more desirable for selection. In at least some embodiments a WCT 220 DL (shown as a dashed arrow) parameters are more desirable than the WCT 221 DL parameters and an UL access traffic (WCT 222) associated with UE 212 is network connected through bUE device 210. In at least some embodiments a WCT 220 UL (shown as a solid arrow) parameters are less desirable than the WCT 221 UL parameters and DL access traffic (WCT 222) associated with UE 212 is network connected through bUE device 211. For example WCT parameters relevant for selecting a bUE device based on bUE WCT include one or more of a link quality, link quality statistics, link quality variation, path loss, fading, shadowing, Signal to Noise Ratio (SNR), Signal to Interference and Noise Ratio (SINR), Packet Error Rate (PER), received interference, interference generated to other devices, Channel Quality Indicator (CQI), Channel State Information (CSI), Modulation and Coding Scheme (MCS), Precoding Matrix Indicator (PMI), rank indicator (RI), single user or multiuser Multiple Input Multiple Output (SU-MIMO or MU-MIMO) information.

For at least one embodiment, the BS 201 is further operative to obtain one or more second parameters associated with the at least one data network (such as, data networks 241, 242) through at least the second communication technology. More specifically, for at least one embodiment, the selection of the one or more of the plurality of bUE devices 210, 211 for the BH traffic is based on the one or more second parameters. A non-exhaustive list of exemplary second parameters includes one or more of a link quality, bandwidth, throughput, cost, latency, jitter, QoS, PER.

In at least some embodiments selecting the bUE device is based on a bUE device backhaul CT parameter (second parameter associated with second communication technology) between the plurality of bUE devices 210, 211 and one or more data networks. For example bUE device 210 may include a backhaul CT 230 with large bandwidth (exemplary second parameter) (for example cable modem) and bUE device 211 may include a backhaul CT 231 with low latency (exemplary second parameter) (for example T1). For this example bUE device 210 may be better suited for a streaming video application and bUE device 211 may be better suited for a VoIP or gaming application. For example bUE device 210 may include a backhaul CT 230 with a monthly data cap (exemplary second parameter) (for example cable modem) and bUE device 211 may include a backhaul CT 231 with unlimited data usage (exemplary second parameter) and high latency (exemplary second parameter) (for example a home DSL). For this example bUE device 210 may be better suited for VoIP or gaming and bUE device 211 may be better suited for background data (for example software updates or local content preloading) application.

For at least one embodiment, the access traffic associated with the one or more UE devices (such as, UE device 212) is classified into two or more data flows based on a data flow parameter and the selection of the one or more plurality of bUE devices 210, 211 for the BH traffic is based in part on the data flow parameter. More specifically, for at least one embodiment, the data flow parameter includes one or more of a data flow bandwidth, latency, Quality of Service (QoS), PER, UE device state, application, user state, cost, sponsoring, data plan. For at least one embodiment a UE device has a plurality of applications using communication resources over the access WCT and at least two data communications associated with the plurality of active applications have a common a data flow parameter within a tolerance threshold. For example a first data communication may be associated with a gaming application with maximum latency of requirement parameter 5 ms and a second data communication may be associated with a VoIP application with maximum latency requirement of 10 ms and the classification is all data flow with latency requirements below 10 ms. For at least one embodiment the data flow classification includes a plurality of parameters, for example bandwidth and latency, or bandwidth and cost, or QoS and cost. For at least one embodiment the plurality of applications includes a plurality of UE devices. For example a first data communication associated with a first application associated with a first UE device may be aggregated with a second data communication associated with a second application associated with a second UE device when they first and second data communications based on a data flow parameter (for example the data flow parameter requirements are within a threshold tolerance).

FIG. 3 shows an embodiment of the backhaul system wherein a BS 301 is further operable to communicate with at least one data network (such as, data network 340) over at least a third communication technology (for example Backhaul CT 332).

For at least one embodiment, the third communication technology for BH traffic includes a carrier grade communication technology. For at least one embodiment, the BH traffic of the third communication technology includes legacy access traffic. For at least one embodiment the BH traffic of the third communication technology 332 includes legacy access traffic, wherein the legacy access traffic includes one or more of 2G access WCT traffic, 2G+3G access WCT traffic, low latency access WCT traffic. For at least one embodiment the BH traffic of the third communication technology includes low bandwidth or low latency access traffic, wherein the access traffic includes one or more of 2G access traffic, 2G+3G access traffic, access traffic associated with voice or gamming applications or real time applications.

In at least some embodiments the BS 301 includes traditional backhaul (for example carrier grade or narrowband—such as a small number of T1 or E1) that is insufficient to satisfy the access traffic demands of the plurality of UE (such as, UE 212). For example a BS 301 that is upgraded from 3G WCT to 3G+4G WCT may not have sufficient bandwidth to support the additional services or applications. For example the BS 301 may include a small number of T1 (for example based on legacy 2G or 3G requirements) that may be able to support latency or jitter or PER requirements (for example for a 2G or 3G cellular service) but may not be able to support the bandwidth requirement of additional 4G services. For example a BS 301 may have been dimensioned for a small number of UE devices or UE devices with lower access traffic capability but over the deployment lifetime a growth in the number of UE devices or additional enhanced access traffic generating capability UE device (for example smartphones or tablets) or additional services or applications on existing UE device may require additional demands on backhaul. In at least some embodiments the BS 301 requires a bUE device 210 to network connect at least a portion of the access traffic (for example additional access traffic from new UE, services or higher bandwidth WCT) to a data network over a bUE device and selecting between the traditional backhaul 332 and the bUE device 210 backhaul. In at least some embodiments the bUE device backhaul is used as an interim solution. In at least some embodiments the bUE device backhaul is used as an interim solution until additional traditional backhaul is available (for example while upgrading a BS backhaul from one or more of T1 to microwave or fiber communication technology). For example a BS deployment with 2G or 2G+3G WCT may be been equipped with a small number of T1/E1, wherein the small number of T1/E1 is sufficient to satisfy an initial or legacy access traffic parameters/requirement (for example bandwidth and latency). For at least one embodiment additional backhaul CT performance (bandwidth, capacity, latency, etc.) is required (for example to include additional UE devices, additional services, additional UE device with enhanced requirements/capabilities, additional WCT—such as 4G) may be required at a later time, wherein the additional backhaul CT performance is achieved with assistance of one or more bUE device 210. For at least one embodiment the additional backhaul CT performance is achieved with assistance of one or more bUE device 210 as in interim solution. For at least one embodiment the interim solution is used until the BS backhaul is upgraded (for example from a small number of T1/E1 to a fiber CT—which may take several years to deploy/install). At least some embodiments of both FIG. 2 and FIG. 3 can implement these embodiments.

For at least one embodiment, the BS 201 (or 301) operative to aid in selecting the transmission power level of at least one of the plurality of bUE devices 210, 211, or the one or more UE devices (such as, UE device 212) is assisted by a signal transmitted by the BS 201 (or 310).

For at least one embodiment the BS 201 (or 310) estimates a received signal strength (for example based on one or more of a pilot, a synchronization sequence, a reference symbol, a training sequence, a data symbol) from at least one of the plurality of bUE devices or at least one of the one or more UE devices and/or derives a transmission path loss from which a desired transmission power level for at least one of the bUE device or UE device may be selected. For at least one embodiment, information associated with the particular bUE device or UE device desired transmission power may be communicated to the particular bUE device or UE device over a control message from the BS 201 (or 310).

For at least one embodiment the bUE devices are selected from the one or more UE devices based on enhanced (or alternatively higher performance or favorable) WCT parameters. For example the bUE device may be selected from the population of one or more UE devices based on better path loss (less path loss), higher MCS, lower PER. For at least one embodiment the bUE device may be a dedicated device with hardware or software functionality that results in better WCT parameters. For at least one embodiment the dedicated bUE device have better antennas (for example higher gain or more antennas), higher transmission power or lower receiver sensitivity or are installed at favorable locations relative to the BS 201 (for example lower shadowing or higher K-factor channels). At least some embodiments of both FIG. 2 and FIG. 3 can implement these embodiments.

At least one embodiment further includes classifying and prioritizing the BH traffic based on the access traffic (for example access traffic is classified based on QoS parameters of the access traffic data or control payload and this information is mapped onto associated BH traffic), and wherein the RB scheduling information for the BH traffic is based on the BH traffic prioritization. At least one embodiment further includes classifying and prioritizing the access traffic, wherein the RB scheduling information for the access traffic and the BH traffic is based on the access traffic prioritization and BH traffic prioritization. For example a DL scheduler may assign RBs to DL access traffic for a first UE device and DL backhaul traffic for a bUE device which includes UL access traffic from a second UE (or the first UE) to be sent over the bUE device backhaul CT. For this example the DL scheduler RB assignments may be based on the first UE DL access traffic classification and the DL backhaul traffic which is associated with second UE (or first UE) UL access traffic. For at least one embodiment, classifying the BH traffic includes best effort access traffic having a lower priority than classified access traffic having a delay QoS below a threshold. At least some embodiments of both FIG. 2 and FIG. 3 can implement these embodiments.

In at least some embodiments the classified aggregated traffic is assigned into queues prior to assigning of resource blocks for BH traffic of at least one of the plurality of bUE devices. For example the VoIP access traffic from the plurality of UE (such as, UE 212) could be assigned to one VoIP queue and based on the plurality of bUE WCT or CT parameters this queue may be carried by a selected bUE device.

For example bUE devices 210, 211 may be selected from a larger pool of available bUE devices for providing backhaul traffic functionality or alternatively bUE devices 210, 211 may have been deployed at desirable locations based on favorable WCT parameters (for example near a BS or with favorably channel parameters—for example one or more of low loss, low interference, etc.) or backhaul CT parameters (for example near a fiber CT with high bandwidth and low latency or near a microwave CT with line of sight—LOS). More specifically, for at least one embodiment, the bUE device deployment selection includes one or more of selecting a bUE device deployment configuration, selecting a bUE device type, selecting a bUE device configuration, selecting a bUE device installation positioning, selecting a bUE device site.

For example BS1 allocates contiguous RB between time units 1 to 5. For example BS2 allocates time unit 1 and has a gap until units 5-6. BS3 allocated time units 1-2. A receiver (for example UE1) may receive a linear combination of all three BS transmissions, attenuated by respective gains G1, G2 and G3. From this example the interference will be worst at time unit (or slot) 1, since all three BS are active and interference would be minimum at time units 7 and 8. Other time units 2 through 6 would have intermediate interference levels. From this example the measured interference is a function of the resource block that is selected for measuring interference and is dependent on scheduling decisions (and traffic load) of the interfering BS. For at least one embodiment it may be advantageous to schedule a resource block and a transmit mode so that the interference measurement at UE1 has less variability. For at least one embodiment improved interference measurements results in one or more of improved resource allocation and improved MCS selection, lower PER, reduced retransmissions for UE1.

FIG. 17 shows a plurality of BS cells, according to an embodiment. In this example (and following figures) all cells are homogenous hexagons for simplicity of representation. In practice BS cells may be heterogeneous (for example different sizes and shapes) and a smaller BS cell (for example micro, pico, femto, or relay node) may be within the coverage area of a larger cell (for example macro or micro). In this example (and several following figures) a cell with a scheduled null transmission is represented as a blank (or white) hexagon. In this example (and several following figures) a cell with a scheduled transmission mode is represented as a diagonally hatched hexagon. In this example (and several following figures) a cell that is not constrained to a transmission mode or a null transmission is represented as a horizontally hatched hexagon. In the example of FIG. 17, a receiver in BS1 (UL) or a receiver of a plurality of UE devices (DL) wirelessly communicating with BS1 may measure joint interference from all six nearest neighboring BS: BS2-BS7 which have all been scheduled to follow a transmission mode. For at least one embodiment all remaining farther neighbors are unrestricted and may transmit (or not) based on local traffic requirements. In the example of FIG. 17 BS1 (or all the UE devices associated with BS1 for UL measurements at BS1) is scheduled to transmit a null transmission. For at least one embodiment a null transmission reduced the complexity of estimating interference. For at least one embodiment BS1 (or a selected UE device) may transmit and the interference may be estimated after subtracting the contribution of the desired signal.

For at least one embodiment simultaneous scheduling of transmission active and null modes with a reuse factor (or minimum separation or cluster size) increases interference measurement rate or transmission efficiencies.

For at least one embodiment a resource allocation or scheduler agent (for example executed by a BS controller) clusters (for example allocates contiguous frequency and/or time resource blocks) transmission modes within a transmission frame (for example DL or UL frames or sub-frames). For example a first set (or alternatively group or cluster or classification) of transmission time slots (or alternatively time and/or frequency RBs) may be assigned a beamforming transmission mode, followed by a second set of transmission time slots assigned a MIMO (multiple input, multiple output) transmission mode, followed by a third set of transmission time slots assigned a SISO (single input, single output) transmission mode, followed by empty slots. In at least a second embodiment a first set of RB may include transmission at a maximum transmit power level, followed by a median transmit power level, followed by a minimum transmit power level. Other group classifications criteria may be based on one or more of path loss (for example for UL), MCS, transmit power, number of transmit antennas, SFR, FFR. For at least one embodiment a plurality of UE device (or bUE device) may be classified into sets based on path loss, for example with high path loss UL UE (which typically will transmit higher power) transmitting the first cluster of RB, followed by typical path loss UE, followed by low path loss UE.

For at least one embodiment a plurality of UE devices (or bUE devices) may be classified into sets based on distance to a BS (or location relative to two neighboring BS), for example cell edge UL UE (which typically will transmit higher power and/or often interfere with a neighboring BS) transmitting the first cluster of RB, followed by median cell UE device, followed by close-in UE device.

For at least one embodiment classifying transmission mode into clusters reduces the variation of interference generated or received over time or enables more predictable interference levels versus frame location (for example time and/or frequency RB relative to frame boundaries) making scheduling or link adaptation more robust based on frame location interference characterization information. For at least one embodiment reduced interference variation based on transmission mode clustering enables resource allocation (for example frequency channel assignments, SFR, FFR) to be allocated at larger time intervals (for example higher latency feedback, more accurate estimators, larger time constant assignments—for example at central or distributed controller at a cloud node). For at least one embodiment a resource allocation or schedulers is based on an inner and outer loop control. For example outer loop (typically resource allocation agent) based on longer term S and/or I statistics, and inner loop (typically scheduler) based on instantaneous channel or queue status.

For at least one embodiment a bUE device is managed (or alternatively controlled) at least in part by a user (for example a cellular subscriber). For at least one embodiment a user may one or more of allow, block, restrict, a bUE device functionality. For example a bUE device user (or subscriber) may limit the amount of backhaul traffic communicating over the bUE device. For at least one embodiment the bUE device may restrict the amount of backhaul traffic based on bUE device state (for example battery state or a data plan associated with the bUE WCT or CT). For at least one embodiment the bUE device includes a user policy. For example a UI for user notification of bUE device information (status, usage, battery usage or projections, etc.), user control (for example one or more of request for permission, approval, block, restrict, allow, throttle, shape) or offers to the user, such as a data plan sponsor. For at least one embodiment the user-managed bUE device is sponsored or awards credits and/or points to the user.

For at least one embodiment a wireless access provider (or WCT provider) pays (or alternatively compensates or is billed by) a second CT provider (for example a cellular carrier may compensate a DSL and/or cable service provider backhauling data through the bUE device). For at least one embodiment, revenue generated from access traffic over backhaul CT is revenue-shared between the WCT provider and one or more backhaul CT provider or some other partnership.
